Solution Overview

Problem

Conventional methods for removing solid state drives (SSDs) from small-sized portable electronic devices, such as notebook computers, are inconvenient due to small openings and non-reusable pulling mechanisms, making it difficult to assemble and disassemble storage devices efficiently.

Innovation Solution

A removable mechanism featuring a rotary pulling rod and driving rod system, where the pulling rod is pivoted to the driving rod, allowing the SSD to be easily ejected from the device by rotating and pulling, utilizing a first rail for guidance and reducing friction with plastic components for smoother operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a small size host is used to accommodate small size SSD, then the device size is reduced, but the opening dimension becomes too small for convenient SSD removal

Engineering Contradiction:
Improvedevice sizeVSAvoidconvenience of SSD removal
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

A pulling rod is introduced as an intermediary tool that extends through the small opening to bridge the gap between the user's hand and the SSD. The pulling rod acts as a mediator that allows the user to grip and remove the SSD despite the opening being too small for direct hand access.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The pulling rod is designed to rotate from a horizontal position (stored within the host) to a vertical position (extending outward through the opening). This dimensional change allows the pulling mechanism to transition from a compact storage state to an extended operational state, enabling SSD removal through the small opening.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a conventional pulling belt made of mylar material is used to draw out the SSD, then the SSD can be removed, but the pulling belt cannot be reused on other hard disks

Engineering Contradiction:
ImproveSSD removal capabilityVSAvoidreusability of pulling mechanism
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The pulling rod is designed as a universal tool that can be used with multiple different SSDs and hard disks. Unlike the conventional mylar belt that is specific to one SSD, the pulling rod serves as a reusable, multi-functional tool that can draw out various storage devices through the standardized opening mechanism.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Instead of attaching a disposable pulling element to each SSD, the design uses a permanent pulling rod that remains with the host device. This rod serves as a reusable copy of the pulling function that can be applied to multiple different SSDs, eliminating the need for new pulling materials with each device exchange.

Inventive Principle:
Principle #26Copying

3Reliability

If the SSD is disposed on a position away from the opening for waterproof and dustproof functions, then sealing is improved, but the opening dimension becomes smaller and removal becomes difficult

Engineering Contradiction:
Improvewaterproof and dustproof functionVSAvoidconvenience of SSD removal
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The pulling rod serves as an intermediary that extends the user's reach through the small opening created by the sealed design. This mediator allows interaction with the SSD positioned away from the opening without compromising the waterproof and dustproof sealing of the host device.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The removal mechanism is segmented into two functional parts: the pulling rod that extends through the opening for user interaction, and the SSD that remains positioned away from the opening for sealing. This segmentation allows the opening to be small for waterproofing while still enabling removal through the extended pulling rod.

Inventive Principle:
Principle #1Segmentation

AI summary

A removable mechanism for drawing an object from a housing is disclosed. The removable mechanism includes a first rail disposed inside the housing and on a side of the object for guiding the object to move inside the housing. The removable mechanism further includes a driving rod installed on the first rail in a movable manner for driving the object to move in a first direction, and a pull rod pivoted to the driving rod for pulling the driving rod to drive the object to move in the first direction so as to eject from the housing when being rotated out of the housing and being pulled.
